Available in PDF, EPUB and Kindle. Book excerpt: This report describes an investigation conducted for the purpose of evaluating an experimental quantity of commercially fabricated plastic mat. The mat is a sandwich structure fabricated from glass-fabric-reinforced honeycomb core material bonded on top and bottom with epoxy adhesive to polyester-resin-impregnated, glass-fabric, laminated facings. Glass-fabric-reinforced tongue-and-groove side and end connectors are fabricated as integral parts of the panels. Laboratory and engineering traffic tests were conducted to determine various properties of the mat in an overall evaluation for comparison with the original T12 mat and with the project requirements. The service-life criteria under which the mat was tested required 200 coverages of a 25,000-lb single-wheel load with a tire-inflation pressure of 250 psi when placed on a subgrade with a California Bearing Ratio (CBR) of 4. This was more critical than the original criteria under which the T12 was tested, which specified 700 coverages of a 50,000-lb single-wheel load with tire-inflation pressures up to 200 psi when placed on a 15-CBR subgrade.

Available in PDF, EPUB and Kindle. Book excerpt: An experimental, commercially fabricated, plastic landing mat designated the T12 was subjected to laboratory tests to determine its structural properties and engineering traffic tests to compare its performance with that of standard M8 steel mat and with project requirements. The laboratory tests indicated that because of fabrication deficiencies the structural properties of the T12 mat were less than considered necessary to fulfill project traffic requirements (700 coverages of 50,000-lb wheel lead with mat placed on subgrade with CBR of 15). Traffic tests (loads of 25,000-50,000 lb, tire pressures of 100-200 psi, on mat-surfaced subgrades with CBR's of 15-17) revealed that the T12 mat as fabricated will not meet project requirements but will sustain two weeks emergency operational category traffic (40 coverages, 50,000-lb load). It is concluded that plastic mat meeting project requirements can be fabricated commercially, and it is recommended that the T12 mat design be modified to incorporate improved connectors and materials and such other improvements as discussed herein and that engineering tests be conducted of the revised design.

Book excerpt: An investigation was conducted at the U.S. Army Engineer Waterways Experiment Station (WES) to evaluate a commercially fabricated, plastic mat designated as the T14. The mat is a sandwich-type structure fabricated from epoxy-impregnated, high-density, foam-filled, glass-reinforced core material and glass, filament-wound, glass-fiber facings impregnated with polyester resin. The panels have extruded aluminum side and end connectors secured to the panel edges by the filament winding female connectors. End connections are made with locking-type connectors that are secured by aluminum locking beams. The investigation consisted of both laboratory and engineering traffic tests to determine various properties of the mat in an overall evaluation for comparison with previously tested mats and with project requirements. The results of the laboratory tests indicated that the mat as fabricated failed to meet all technical design requirements of the technical specifications. However, since the mat represented a new design concept, it was traffic tested to complete the evaluation of the design and fabrication. During traffic tests, the T14 mat placed on a 4.2-CBR subgrade sustained a maximum of 12 coverages of a 25,000-lb single-wheel load with 250-psi tire pressure, thus failing to meet it was calculated that an 11.5-CBR subgrade would be required to support the mat for 200 coverages. In view of the more severe operational requirements for present-day airfield surfacing, it was concluded that a reevaluation of new plastic mat designs, fabrication techniques, and plastics technology should be made prior to procurement of any additional plastic loading mats for testing.
